4 Claims.

In the construction of ships and like vessels, it is customary to employbulkheads made of metal sheets or plates, which are overlapped andriveted or otherwise secured together. The overlapped junction of theplates, adjacent the deck, is usually encased in a baseboard or baseplate which as now used, is cumbersome and bulky in that the baseboardor plate must first be mounted on a plastic levelling guide and expandedmetal interposed between the baseboard and bulkhead, which serves toreinforce a plastic composition deposited between the baseboard andbulkhead. With the device of the present invention we provide a compact,durable and less expensive medium of encasing the overlapped joint ofthe bulkhead near the ships deck, at the same time providing a baseboardor plate which is selflevelling.

Another object of the invention is to provide a baseboard or plateespecially adapted for use on ships which may be mounted directly on theships deck, contiguous to the bulkhead, instead of spaced therefrom ashas heretofore been done, the base plate being so formed that when thefloor is poured, a substantially monolithic structure is provided.

Although the device of the present invention is especially adapted foruse on ships, it is of course, to be understood that it may be used as abaseboard in building structures in a manner well known in the art.

Other objects of the invention will be apparent from the followingdescription thereof, taken in connection with the accompanying drawing,wherein Fig. 1 is a perspective view of baseboards or plates constructedin accordance with the present invention, illustrating the applicationthereof; and

Fig. 2 is a perspective view of one of the base plates, per se.

For the purpose of illustrating the application of the invention, wehave, in Fig. 1, shown a ships deck 3, upon which a bulkhead is mountedthe bulkhead embodying a pair of sheets or plates 4 and 5 which may besecured together in a manner well known in the art.

The baseboard or plate constructed in accordance with the presentinvention is shown to advantage in Fig. 2 and consists of a verticalbase portion 6, the sides of which are straight. The body of the boardor plate, designated 7, issues from the top of the base 6 and islaterally offset therefrom, the upper terminals of the body beingdisposed at right angles to provide a lip or flange 8. It will be notedthat the inner face of the body portion '7 of the plate is straight, inorder to abut the outer face of the lowermost bulkhead sheet 4 from apoint in proximity to the lip 8 to the base 6. The lip 8 overhangs thetop of the sheet 4, but is preferably spaced from the bulkhead sheet 5to provide a groove or pocket between the base plate and bulkhead,adapted for the reception of a plastic composition 9. Furthermore, itwill be noted upon reference to Fig. 1 of the drawing, that 55 a spaceis provided between the base 6 and the sheet 4 of the bulkhead toprovide a channel in which, if desired, a plastic composition 10 may beinterposed.

Preferably the outer side of the base plate 7 is roughened to insureadherence of the plastic floor of the ship thereto. We prefer in thisconnection to provide longitudinally extending grooves 11 in the outerface of the base, which are V-shaped in cross-section and receive theplastic composition used in a floor 12, which latter is superimposed onthe deck 3. It will be noted that the top of the floor is uniplanar withthe top of the base 6, which latter curves inwardly to provide an arethereby eliminating the possibility of materials gathering in thejuncture between the surface of the floor and the base plate.

In employing a base plate of the present construction, it is manifestthat the plate may be mounted directly on the ships deck and if desired,the plastic composition poured therebetween and the sheet 4 of thebulkhead. The plate is urged into contiguous relationship with saidplate 4, in order to be positioned substantially as shown in Fig. 1 ofthe drawing. The plastic composition 9 interposed between the lip 8 and.the sheet 5 of the bulkhead, serves to bond the plate to the bulkheadand at the same time provides a filler to prevent extraneous materialsfrom finding their way between the top of the base plate and thebulkhead. The floor 12 constantly urges the base plate toward thebulkhead, preventing any dislodgment of the plate.

Although the base plates constructed in accordance with the presentinvention are preferably formed from plastic material, it isnevertheless to be understood that various other materials may be usedwithin the spirit and scope of the invention. Furthermore, variouschanges may be made therein, especially in the details of construction,proportion and arrangement oi parts, within the scope of the appendedclaims.

What is claimed is:

1. In combination with a bulkhead embodying overlapped nonplanar sheets,a base plate for engagement over said sheets at their point ofoverlapping including a plate body, a portion of one side of which iscontiguous to one of said sheets, a further portion of said plateoverhanging the top of said sheet in spaced relationship to the othersheet of the bulkhead, and a plastic composition disposed on the top ofsaid first sheet between said other sheet of the bulkhead and theoverhanging portion of the plate.

2. A base plate for building structures having plastic floors includingan integral body having a vertical base portion, the opposite sides ofwhich are straight, one of said sides having grooves formed therein forthe reception of the plastic floor composition, the body of the plateissuing from the top of said base portion and offset laterallytherefrom, the upper terminal of the body being turned at right anglesto the latter and having a straight inner face.

3. In combination with a bulkhead embodying overlapped upper and lowernonplanar sheets, a base plate for engagement over the overlappedmargins of said sheets including a plate body mounted on the deck, anintermediate portion of one face of said body engaging the lower of thesheets, the lower part of said face being spaced from the lower sheet toprovide a channel, the upper margin of the base plate overhanging thetop of the lower sheet in spaced relation thereto and the upper sheet.

4. A base plate for building structures, including a relatively widebase for direct engagement with a floor of the building structure, thetop of the base issuing vertically into an upper portion which is in thesame vertical plane with the base and equipped with a laterally offsetportion, the upper terminal of said vertically issuing portion beingalso laterally offset, the inner faces of said base and two laterallyoffset portions being straight and lying in three different verticalplanes, the outer face of the base plate being straight while the outerface of the portion issuing from the base is curved.
